8.43); an isochasm is a line of equal frequency of an unusual or frightening
apparition. The isochasms were found to be ovals around the geomagnetic pole
with the maximum at geomagnetic latitudes around 70°. For the auroral oval

The auroral zone is defined either as the region in the vicinity of the maximum
isochasm or the region where auroras are observed most frequently at the zenith
and more rarely to the south and north of it [1, 2] , or that region where an aurora

... the antipode of the northern dip pole. It is now possible to draw the curve of the
maximum isochasm from certain theoretical considerations, one point on it being
known. This has been done with success for the northern maximum isochasm.
"Outermost" means farthest from the magnetic center. The aurora may or may not
be visible from the ground at this position, and may be visible from other places.
An isochasm is here defined to be a line (probably one of a pair) connecting ...

The maps show also the L lines (McIlwain, 1961), which appear to be closely
related to the isochaams or lines of equal frequency of auroral visibility (in the
average over many years). The isochasm of maximum frequency is the centre
line of ...
